You’ve seen the ads: ancestry tests that can link you to long-lost relatives and, with just a small saliva sample, map your roots. I took the test
I am not British. This came as a bit of surprise to me, given I was born in London to parents who had themselves been born in London, with a family history as pub tenants in the East End going back to the 1860s at least.

But how much should we trust these DNA kits that are so widely advertised on television – and crucially, what do they do with our deeply personal DNA data? Share it with anyone else on the globe seems to be the answer.
